Leon wrote an expression that is equivalent to (30 + 6) ÷ 12. Which expression could be the one Leon wrote?

Answer: (a) (i)50.42 m/s (ii) 51.35 m/s (iii) 52.094 m/s (iv) 52.2614 m/s (v) 52.27814 m/s

(b) 54.14 m/s

Step-by-step explanation:

The average speed over the given time interval [a,b]: = [tex]\frac{y(b)-y(a)}{b-a}[/tex]

Given: If an arrow is shot upward on Mars with a speed of 56 m/s, its height in meters t seconds later is given by [tex]y = 56t − 1.86t^2.[/tex]

(a)

(i) average speed = [tex]\frac{y(2)-y(1)}{2-1}[/tex]

[tex]=\frac{56(2)-1.86(2)^2-(56(1)-1.86(1)^2)}{1}[/tex]

[tex]=50.42[/tex] m/s

(ii) average speed = [tex]\frac{y(1.5)-y(1)}{1.5-1}[/tex]

[tex]=\frac{56(1.5)-1.86(1.5)^2-(56(1)-1.86(1)^2)}{0.5}[/tex]

[tex]=51.35[/tex]m/s

(iii) average speed = [tex]\frac{y(1.1)-y(1)}{1.1-1}[/tex]

[tex]=\frac{56(1.1)-1.86(1.1)^2-(56(1)-1.86(1)^2)}{0.1}[/tex]

[tex]=52.094[/tex]m/s

(iv) average speed = [tex]\frac{y(1.01)-y(1)}{1.01-01}[/tex]

[tex]=\frac{56(1.01)-1.86(1.01)^2-(56(1)-1.86(1)^2)}{0.01}[/tex]

[tex]=52.2614 [/tex]m/s

(v) average speed = [tex]\frac{y(1.001)-y(1)}{1.001-01}[/tex]

[tex]=\frac{56(1.001)-1.86(1.001)^2-(56(1)-1.86(1)^2)}{0.001}[/tex]

[tex]=52.27814 [/tex]m/s

(b) [tex]y(1)=56(1)-1.86(1)^2[/tex]

[tex]=56-1.86[/tex]

[tex]= 54.14[/tex] m/s

plz rate 5 star + thanks i need 1 brainliest to reach in expert

Answer:

The average rate of change is 0

Step-by-step explanation:

Given

See attachment for graph

Required

The average rate function for [tex]0 \le x \le 8[/tex]

The average rate function (m) is calculated as:

[tex]m = \frac{f(b)-f(a)}{b - a}[/tex]

for [tex]a \le x \le b[/tex]

So, we have:

[tex]a =0[/tex]

[tex]b = 8[/tex]

This gives:

[tex]m = \frac{f(b)-f(a)}{b - a}[/tex]

[tex]m = \frac{f(8) - f(0)}{8 - 0)}[/tex]

[tex]m = \frac{f(8) - f(0)}{8}[/tex]

From the attached plot;

[tex]f(8) =0[/tex]

[tex]f(0) = 0[/tex]

So, we have:

[tex]m = \frac{f(8) - f(0)}{8}[/tex]

[tex]m = \frac{0}{8}[/tex]

[tex]m = 0[/tex]

Answer:

B. 30

Step-by-step explanation:

Given.:

m<4 = 2x°

m<5 = 4x°

Required:

Value of x

Solution:

<4 and <5 are angles in a straight line, therefore:

m<4 + m<5 = 180°

Substitute

2x + 4x = 180°

6x = 180°

x = 180/60

x = 30

Answer: 904.779

Step-by-step explanation:

v = pi x radius^2 x height

Answer:

904.78 cm^3

Step-by-step explanation:

The formula for volume of a cylinder is V = π r^2 h, and when you plug in your measurements you get the equation V = π × 6^2 × 8, which equals 904.78 cm^3

Answer:

7.48 in.

Step-by-step explanation:

Given :-

And we need to find out the second leg. So here we can use the Pythagoras Theorem , which establish the relationship between the sides of a right angled triangle. As ,

[tex]:\implies[/tex] p² + b² = h²

[tex]:\implies[/tex] 5² + b² = 9²

[tex]:\implies[/tex] 25 + b² = 81

[tex]:\implies[/tex]b² = 81 -25

[tex]:\implies[/tex] b² = 56

[tex]:\implies[/tex] b = 7.48 in

Hence the measurement of second leg is 7.48 inches .

equation:3.25x+1.2=40.2

ansrew:x=12

Answer:

b=40

Step-by-step explanation:

You need to solve this because it is b divided by 2. How you solve this is to multiply all of it by 2. 20 x 2 is 40.

Answer:

area of 105° segment = 74.2 in²

Step-by-step explanation:

area of entire circle = πr² = (3.14)(9²) = 254.34 in²

area of 105° segment = (105/360)(254.34) = 74.2 in²

Step-by-step explanation:

28<18-5(-3)= 28<33 T

28<18-5(-2)= 28<28 F

28<18-5(-1)= 28< 23 F

28<18-5(0)= 28<18 F

28<18-5(2)= 28<8 F

-3(14)/-51<1 =0.82<1 T

-3(15)/-51<1=0.88<1 T

-3(17)/-51<1=1<1 F

-3(18)/-51<1= 1.1<1 F

-3(19)/-51<1=1.1<1 F

-3,14,15

The answer is

Answer:

82.7

Step-by-step explanation:

Answer: the answer is that the mean would become smaller.

Step-by-step explanation: if you have the original 9 values, the mean is 85.5 repeating. Adding 65 and 75 to the data set changes the mean to 82.72 repeating.

Answer: 1/3 quart

Step-by-step explanation: since they both have the same denominator, you can just do 5-2=3. that gives you 3/9, which can be simplified by dividing both the numerator and denominator by 3 which equals 1/3.

Answer:

The third one.

Step-by-step explanation:

The first graph says each square is 10 lunches, but there are only 3 squares for the deli sandwich. That's 30 deli sandwiches in total but there were 300 in the table so the first one is wrong. In the second one, it says that 2 types of lunches were sold up to 300 times, but in the table, only 1 was. The last graph says that there were 300 pizzas sold, but the table said there were 650, so that one is wrong.

Process of elimination leaves you with the third graph as the correct answer.
